To all whom it may concern; I 7

Be it known that I, ALBERrBRoADMEYER, a citizen of the United States, residing at Harrisburg, inthe county of Dauphin and State of Pennsylvania, haveinvented certain new anduseful Improvements- Gage or Gate Mechanisms,'of which. they following'is a s ecification. 4 W p p he present lnvention relates to means for determining the passage of ,paper or .other work into ruling machines and the like I c c -The object is to provide a relatively simple-structure, which can be adjustedso as to insure its proper operation and synchronism with the other mechanisms'of the machine. An embodiment of the invention which is at present considered the preferable one,-is illustrated in the accompanying drawings, wherein Figure 1 is 'a plan viewof the gage with porticns shownin section. I

Similar reference numeralsde'signate corresponding parts in all the figures of the drawings.

In the embodiment illustrated, a suitable supporting frameis employed, portions of the lon itudinal frame bars being. illustrated at 7. etween these frame bars-operates a work-conveying belt, a port-ion of which is illustrated at. S. Upon this belt are a plurality. of longitudinally disposed cords .9

that serveto holdfthe work in the form of papersheetsor the like againstslipping during. the passage of, such sheets through the machine. A plurality of rollers 10,. 1'1 and 12 support the belt 8 in the frame the rollers'being j ournaled in boxes 13 slidable in guideways let' formedin brackets 1"5f that are securedtothe inner sides of" the frame bars 7. Theboxesare vertically adjusted by b means of screws 16 journaled inthe brackets tion bya set screw 24 Specificationof Letterslatent. Pate t d J 22 1920; Application filed September. 22, 1919.

and having threaded engagement with said boxes. I

Mounted longitudinally upon the frame bars 7 are base plates 17 having longitudinal guideways 18 in which are mounted slides 19 and 20. The rear slide is normally fixed against movement by a set screw 21, and the front slide is adjusted by a horizontal screw 22 threaded thereinto and having a bearing 23 on one end of the base plate. This screw is held against accidental rotaengaging thereon. Carried by the slides 19 and 20 are standards 25 provided at their upper ends with heads 26 having inwardly'opening. sockets 27.

A rock shaft 28 extends across the conveyer belt 8 and is provided with terminal sockets in whichare slidably located supporting stems 30 that project from the ends of theshaft and have terminalballs 31 lo cated inthe sockets 27, and retained therein by plugs 32. The rock shaft is thus mounted to turn and can be shifted at either or both ends by adjusting the slides 19 and 20.,

Slidably mounted on the rock shaft 23 are collars 33 normally held against sliding movement and against rotation on the rock shaft by set screws 34 passing therethrough and formed longitudinally in the shaft. collars 33 have outstanding ears 36 provided with bores 37 in which are adjust-ably mounted stop fingers 38 that are held in place by set screws 39. The lower ends of these fingers are preferably tapered, as illustrated in Fig.3, and are adapted to move into and out of engagement with the belt 6 between the cords 9, accordingly as the rock shaft is actuated.

Extending longitudinally of one of the frame bars 7, and consequently transverselv of the rock shaft 28'is a main driving shaft 40 on which is mounted a face cam 41, and coiiperating with this face cam, is a depending arm 42 of a bell crank 43, the said arm having journaledon its free terminal a roller 44' that operates against the face of the cam 41. The other arm 45 of the bell crank extends in a generally horizontal direction beneath the shaft 28 and terminates" in a bearing plate 46. Secured to the rock shaft 28 by a set screw 47 is a collar 48 having a crank arm 49 through which is adjustably threaded a bearing screw 50 engaging in a groove or keyway 35 The i that rests upon the plate 46 and is held against accidental displacement by a lock nut 51. The rock shaft 28 has affixed there to another crank arm 52, to the free end of which is connected a spring 53 that is also connected to an ad'ustin screw 54 thread ed into a bracket 55 on the adjacent frame bar 7. The action of this spring is to turn the rock shaftin a direction to raise the stop pins 38 from the belt 8, while the cam when rotated will, through the bell crank 4:3, serve to move the rock shaft ina direction to depress the stop fingers to the belt against the action of the spring. The bell crank 43 is journaled on a pivot stem 56 slidably mounted in a bearing piece 57 that is secured transversely to the upper side of the front frame'bar 7. It is normally held against longitudinal adjustment by a setscrew 58, but when said set screw is loosened, the pivot stem 56 can be moved through the medium of an adjusting screw 59 j ournaled as shown at 60 in the bearing piece 57 and having a threaded engagement in the inner end of said pivot stem.

In operation the cam 4:1, being rotated,

will cause the bell crank to be periodically rocked, and this bell crank constituting an actuating member, will transmit mo tion periodically to the bell crank 49, constituting an actuated memberj 'The stop "fin ers will thus be held for a Jredetermined period upon the belt, and a sheet of paper introduced between the cords 9 and the belt 8 will be moved to a position against said stop fingers. As the cam continues to rotate, the bell crank will be released, per

mitting the spring 53 to act and raise the fingers 38, whereupon the paper will pass on to the other instrumentalities, as for example, ruling mechanism. It will be noted that with this structure the fingers can be individually adjusted toward and from each other, so that they can be properly positioned with respect to the cords 9, and can thus be always placed in non-interfering relation to the cords. T his is particularly useful in ruling mechanism, wherein the cords must in turn be so positioned that the Y will not interfere with the ruling pens. ither end of the rock shaft can be adjusted longitudinally along the conveyor belt, so as to insure that the fingers will all register and be abutted against by the advance edge of the paper. Any defect or discrepancy therefore due to the cutting or shape of the paper can be accommodated. Furthermore the rock shaft can be adjusted bodily by correspondingly moving both slides 19 and 20 in order to insure the proper synchronism of the gage or stop mechanism with the other means that operates on the paper. Furthermore by adjusting the pivot stem through the medium of the screw 59, the position of the roller i l and bell crank 43 can be'varied with respect to the driving cam 41, and in this way the time of action of the gage or gate can bevaried. i

From the foregoing, it is tho'ughtfthat the construction, operation and many .advan tages of, the herein described invention will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
